Re: Truckle slide

Yes that's exactly what I thought so my first effort was to form that mouse hole tiny little micro carb. It didn't work. I can't remember whether it was worse or just no different. As a long shot I blended it out to match the venturi radius and hey presto!

Re: Truckle slide

Thanks for the diagram minetymenace.
Remember to only file to a depth of 1 to 1.5mm max. Any more than that and you'll get a fast idle that you can't reduce.
I'm really looking forward to hearing your results because you seem like someone who is thorough in your approach.

Re: Truckle slide

The filed part is just about 1mm to 1.5mm deep and should follow the radius of the carb throat. The running mixture is not affected at all other than to improve pickup and low rpm running. You might find a slightly different sweet spot for the idle air screw though. If you don't like the results and...

Re: Truckle slide

Yes. It is that simple. I have a Chinese 50cc that fluffed so I did the same mod and it fixed it. There's no risk because in the unlikely event it makes the bike worse just file the skirt down to remove the micro carb or buy a new slide from Amal. My advice is to file small amounts at a time then te...

Re: Truckle slide

Yes. We'll get together sometime. My brother has a 1979 Bonneville with concentric MK2s. He has the same symptoms. Difficult starting and stalling at traffic lights when opening the throttle. I will modify his slides someday to cure that. I had a 1980 Bonneville with exactly the same problems. I fit...

Re: Truckle slide

Here's an update. Amal concentric. If you have poor throttling just off the idle with fluffing and stalling and fussy low rpm behaviour then it can be improved very simply by filing a depression in the bottom of the slide with the same radius as the carb venturi. The optimum depth is somewhere aroun...

Re: Truckle slide

That's a complex shape Beat. Impressive lateral thinking to come up with that solution. <200

Truckle slide

I have a '71 250 Trail Blazer which you can read about in "Members bikes". I have it running really well but had difficulty getting good pickup from idle (called "truckle" by Odane, my Jamaican friend). I tried various different slides from 2 1/2 to 3 1/2 and although I got great performance, pickup...

Re: Be careful what you wish for

A 30mm socket is a snug fit on my 250 Trail Blazer swinging arm nut.

Re: Iron Butt Rally B50. Possible?

Here's my thinking: I'm the wrong side of 60. The Tiger 800 with all its extras and stuff is heavy. If I drop it on some lonely road in France I can't pick it up by myself. I was riding my newly acquired 250 Trail Blazer and thinking "This is comfy. I could do serious miles on this thing. If only it...

Iron Butt Rally B50. Possible?

Hi Guys, Has anyone had long distance experience on a B50? I'm hatching a plan ... Find a tidy B50 Fit Givi Top box and paniers. Use it for next year's Brit Butt Rally 1000 miles in 30 hours. Tour around Europe for a week or so. Is this a possibility or a crazy deluded dream? ...or should I just sti...
